The introduction of a heavy-ion rotating gantry is in progress at the Heavy Ion Medical Accelerator in Chiba (HIMAC) for realizing high-precision cancer therapy using heavy ions. A scanning irradiation method will be applied to this gantry course wit

A superconducting rotating-gantry for carbon-ion radiotherapy was developed. This isocentric rotating gantry can transport carbon ions having the maximum kinetic energy of E = 430 MeV/ u to an isocenter with irradiation angles of over ±180°, and is

We have measured the electrical resistivities and magnetoresistances (MR) of (EDT-DSDTFVO)2X (X = FeCl4, GaCl4), where EDT-DSDTFVO stands for ethylenedithiodiselenadithiafulvalenothioquinone-1,3-dithiolemethide. These materials undergo gradual metal-

It is theoretically predicted that the ground state of the one-dimensional (1D) half-filled system is the Mott insulator at any positive on-site Coulomb interaction U . In this paper, we demonstrate that (TTM-TTP)I 3 with a highly 1D half-filled ener

To explore novel physical phenomena related to strong π-d interaction, we measured the resistivity (p) and magnetoresistance of the first organic ferrimagnetic π-dsystem, (EDT-TTFVO) 2 FeBr 4 under high pressures up to 8 GPa, where EDT-TTFVO denote

The transport properties of organic τ-type conductors seem to be very clean as well as very dirty depending on what we observe. To clarify this problem, we studied temperature and magnetic field dependence of resistivity, ρ(T, B), in τ-(EDO-S,S-DM

We demonstrate that the title compound (TTM-TTP)I3 with a highly one-dimensional half-filled band, which shows a metal-insulator (MI) transition around TMI=120 K, is metallized by application of extremely high pressure (P>7 GPa) using the cubic anvil

We have extensively measured the resistance of NbSe 3 near critical pressure ( P 1 = 3.2 GPa) for the upper charge-density-wave ( T 1 -CDW) phase. We reveal that the T 1 -CDW coexists with the superconducting (SC) phase between 2.0 GPa and 2.9 GPa. N

We measured the charge fraction of 6.0 MeV/n heavy ions (C, Ne, Si, Ar, Fe and Cu) with a carbon foil at the NIRS-HIMAC injector. At this energy they are stripped with a carbon foil before being injected into two synchrotron rings with a maximum ener
